Dunder or magic method to return the type() of the object

There are dunder or magic functions for many things like to get len(), print() we can even use help() without even using a magic function and use ?Class if we have used the proper docstring.

Suppose I have a class like this:

class Node():
    def __init__(self, data):
        self.data = data
        self.next = None
    
    def __repr__(self):
        pass
    
    def __str__(self):
        pass
    
    def __len__(self):
        pass
        
node = Node([1,2,3])
type(node)

When I used the type(), it said __main__Node. What magic method I have to use it to return something like LinkedList.Node or simple Node?? Just like it returns list, str or numpy.ndarray??

type() does not call any magic method. It merely returns the value of instance.__class__ attribute.

Manually overwriting it is not necessarily a good idea. If you want LinkedList.Node instead of __main__Node the best thing to do is to define Node inside a LinkedList module.
